Integrating Tableau to the Execution Service

You need to add the dependency to a built-in library. To do so, edit the extensions/execution-service-extension/build.gradle Gradle configuration file and enrich the dependency block as in the following example:

dependencies {
    ...
    // Tableau
    implementation "com.decisionbrain.gene:execution-tableau-base:${versions.decisionbrain.dbgene}"
}

You also have to create a Java configuration that adds the Tableau refresh task in the Execution Service. To do so, add a TableauTasks class with the @EnableTableauExecution in the execution-service-extension as in the following code:

package com.example.caplan.data.configuration;

import com.decisionbrain.gene.tableau.execution.EnableTableauExecution;
import org.springframework.context.annotation.Configuration;

@Configuration
@EnableTableauExecution // Adds tableau refresh tasks
public class TableauTasks { }

And add the following properties in the Execution Service extension. Edit the file extensions/execution-service-extension/src/main/resources/application.yml and add the following content.

tableau-client: 
   enabled: true 
   host: '<the-url-of-your-Tableau-server>'

For the local development, you will have to add the environment variables to the run configuration of the Execution Service.

  TABLEAU_CLIENT_PERSONAL_ACCESS_TOKEN_NAME='fill-me'
  TABLEAU_CLIENT_PERSONAL_ACCESS_TOKEN_SECRET='fill-me'

For Helm deployment, you must add the following values to your environment values file values-my-cluster-name.yaml. For example:

<your-application-chart-name>:
  executionService:
    env:
      TABLEAU_CLIENT_PERSONAL_ACCESS_TOKEN_NAME:
        value: 'fill-me'
      TABLEAU_CLIENT_PERSONAL_ACCESS_TOKEN_SECRET:
        value: 'fill-me'
